Abstract

BACKGROUND:

Safe systemicprotectionfrom the health hazards ofultravioletradiation (UVR) in sunlight is desirable.Greenteais consumed globally and is reported to have anti-inflammatory properties, which may be mediated through the impact on cyclooxygenase and lipoxygenase pathways. Recent data suggest thatgreenteacatechins(GTCs) reduce acute UVR effects, but human trials examining their photoprotective potential are scarce.

OBJECTIVE:

We performed a double-blind,randomized, placebo-controlledtrialto examine whether GTCs protectagainstclinical, histologic, and biochemical indicators of UVR-inducedinflammation.
